Here are my requirements:
- storing data on country-specific sites (for legal reasons, the data that is going to be indexed needs to physically stay in the country were it got created)
- searching across all sites
My current design is the following:
- 3 completely independent index clusters in different sites with no replication between them
- 1 search head cluster (with a load balancer in front), that would use the 3 indexer clusters as its search peers
Is that even possible?
I think I understood that a single search head can search across several indexer clusters, but I am not entirely sure the search head cluster allows for that.
Also, do I need to add a search head inside each indexer cluster to make this whole system to work? Or should I only do that if I want each indexer cluster to be searchable on its own?
